Ghosts Beneath Us — Kathryn Meyer Griffith

Someone is terrorizing the elderly in a certain neighborhood in Spookie and vandalizing their homes. As usual, Abigail Sutton, a freelance artist, and her boyfriend Frank Lester, a retired homicide detective, are called in to help find out who's doing these awful acts. The two seem to have an uncanny knack for unraveling mysteries and getting to the bottom of such strange happenings. Some of the old people think it's ghosts in their basements, in their homes, doing these destructive deeds but Frank doesn't believe in ghosts; while Abigail isn't so sure. Then the old folks begin to disappear one by one or to die suspiciously and Frank thinks there's a sinister plan behind the crimes and is determined to uncover who or what is responsible. In the end, they, with a little help from their friend eccentric old Myrtle, must solve the mystery or more of the old ones in town might end up dead.
